Soziale Einflüsse auf außerpaarliche Vaterschaften
Biologie des Verhaltens und der Sinne
Zusammenfassung der Projektergebnisse
Phenotypic differences among members of social groups such as sizes, behavioural tendencies, or even different experiences play a key role in shaping population-level processes, including the mating system. In this project we integrated two areas of scientific inquiry: (i) extra-pair mating behaviour, and (ii) social network analysis, to understand how variation in social structure and group composition can shape mating systems. Our project first outlined a framework to study these two areas at unison, and second, generated insights into: (i) why animals differ in their propensity to engage in extra-pair mating behaviour, (ii) how social dynamics drives the expression of mating behaviours and the subsequent patterns of extra-pair paternity across groups or populations, and (iii) the proximate mechanisms that promote, or otherwise shape, extra-pair mating behaviour. The project has been very successful at training young researchers and in producing a number of influential publications. These publications include describing new technological advances for studying social animals, conceptual insights into the links between the social environment and mating systems, the stability and repeatability of social behaviour within groups, provisioning of non-offspring by parents, and the development of social relationships. The project has also inspired a number of studies across a range of taxa, including tests of the hypotheses that we developed in wild blue tits and studies on cultural evolution in great tits that relied on the technological advances made as part of this project. The final output of the project—the role of the social environment in shaping extra-pair paternity and the heritability of social traits—is currently in preparation.
